Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application provides a GPF regeneration control method. Referring to fig. 1, fig. 1 is a flowchart of a GPF regeneration control method according to an embodiment of the present application, as shown in fig. 1, including the following steps:
step 101, detecting carbon content in a gasoline engine particle catcher GPF;
102, under the condition that the carbon content in the GPF meets the preset requirement, sending an engine coordination request to a vehicle control unit VCU, wherein the engine coordination request comprises an engine torque working range and an engine rotating speed working range;
step 103, determining an engine running torque and an engine running rotating speed through the VCU, wherein the engine running torque belongs to the engine torque working range, and the engine running rotating speed belongs to the engine rotating speed working range;
and 104, performing active regeneration control on the GPF according to the engine running torque and the engine running rotating speed.
In the actual vehicle running process, after the vehicle is driven for a period of time, the particulate matters in the gasoline engine particulate trap (Gasoline Particulate Filter, GPF) gradually increase to cause the back pressure of the engine to rise, so that the deposited particulate matters need to be removed periodically to restore the filtering function of the GPF, and carbon in the GPF needs to be subjected to chemical reaction, oxidation and combustion in the process, which is called as the regeneration process of the GPF. The regeneration of the GPF comprises passive regeneration and active regeneration, wherein the passive regeneration refers to that when a driver releases a pedal under a daily driving condition, the engine is cut off, and a large amount of oxygen enters the GPF to realize the regeneration. The active regeneration refers to that under the condition that passive regeneration cannot be met, the vehicle runs to a special working condition, an ECM is utilized to give an engine instruction, the ignition angle is pushed backwards, the tail gas temperature is increased, and after the GPF temperature is increased, the air-fuel ratio (excessive oxygen) is reduced, so that the GPF regeneration is realized.
In the GPF regeneration control method according to the embodiment of the present application, the active regeneration control process of the GPF is mainly extended. Firstly, detecting the carbon content in the GPF, and sending an engine coordination request to a vehicle control unit VCU under the condition that the carbon content in the GPF meets the preset requirement, namely, the carbon content in the GPF exceeds an active regeneration limit value, and triggering an active regeneration control process is required. In actual control, an engine coordination request ems_workpoint_req=1 may be sent to the VCU by an engine management system (Engine Management System, EMS), for example, and this engine coordination request ems_workpoint_req=1 includes an engine torque operating range and an engine speed operating range, where the engine torque operating range may be expressed as follows:
ems_min_work_req < EngSpeed < ems_maxseed_work_req, and the operating range of the engine speed can be expressed as follows:
EMS_MinTorque_workbench_Req < EngTrq < EMS_MaxTorque_workbench_Req. The VCU, upon receipt of the engine coordination request, determines an engine operating torque and an engine operating speed in response to the engine torque operating range and the engine speed operating range. It should be noted that, at this time, the VCU may also send a response signal vcu_strepmodappt=1 to tell the EMS to respond to its request successfully, and if there is no response, send vcu_strepmodappt=0. And under the condition of successful response, performing active regeneration control according to the engine running torque and the engine running rotating speed.
According to the GPF regeneration control method, the VCU is used for determining the engine running rotating speed and the engine running torque during the active regeneration control, and the engine is used for assisting in completing the active regeneration control process, so that the efficiency of the GPF regeneration control method is improved.
Optionally, the sending an engine coordination request to the vehicle controller VCU when the carbon content in the GPF meets a preset requirement includes:
and under the condition that the carbon content in the GPF is larger than a first preset value and smaller than or equal to a second preset value, sending a driving active regeneration request and the engine coordination request to the VCU.
In the GPF regeneration control method of the embodiment of the present application, the active regeneration includes active regeneration during driving, that is, the active regeneration control process is performed during the driving of the vehicle, and it is to be noted that the control process for performing active regeneration during driving needs to have carbon content within a certain numerical range, that is, greater than a first preset value and less than or equal to a second preset value, because the active regeneration control is performed only when the carbon content is greater than the first preset value, and meanwhile, the active regeneration control is required to be less than or equal to the second preset value, because if the carbon content is greater, the relevant regeneration control process cannot be performed during the driving of the vehicle, and the specific sizes of the first preset value and the second preset value are actually determined according to the performance of the vehicle.
The GPF regeneration control method of the embodiment of the application triggers different active regeneration control processes according to the carbon content, and carries out regeneration control according to different conditions, thereby being beneficial to improving the efficiency of the GPF regeneration control method.
Optionally, the determining, by the VCU, an engine operating torque and an engine operating speed, the engine operating torque belonging to the engine torque operating range, the engine operating speed belonging to the engine speed operating range, includes:

In the GPF regeneration control method of the embodiment of the present application, the active regeneration includes parking active regeneration in addition to driving active regeneration, that is, the active regeneration control process is performed during parking, and it is to be noted that the control process for performing parking active regeneration requires that the carbon content be within a certain numerical range, that is, greater than a second preset value, to indicate that the vehicle cannot perform active regeneration by itself during driving. It should be noted that, in this case, the regeneration control needs to be performed by external intervention, and the vehicle needs to enter the parking active regeneration control process after receiving the parking regeneration command sent by the host computer.
In the actual operation process, the vehicle can be driven to a designated place by the vehicle owner, and the parking regeneration control process is triggered by the diagnostic instrument. The GPF regeneration control method of the embodiment of the application triggers different active regeneration control processes according to the carbon content, and carries out regeneration control according to different conditions, thereby being beneficial to improving the efficiency of the GPF regeneration control method.
Optionally, the determining, by the VCU, an engine operating torque and an engine operating speed, the engine operating torque belonging to the engine torque operating range, the engine operating speed belonging to the engine speed operating range, includes:

According to different active regeneration types, the method has the advantages that the engines are correspondingly coordinated, so that the efficiency of the GPF regeneration control method is improved.
Optionally, after the active regeneration control of the GPF according to the engine operating torque and the engine operating speed, the method further includes:
and sending a feedback signal to the VCU, wherein the feedback signal is used for representing the active regeneration state.
In the GPF regeneration control method according to the embodiment of the present application, after the vehicle performs active regeneration control on the GPF according to the engine running torque and the engine running rotational speed determined by the VCU. The state of the active regeneration control needs to be fed back to the VCU so that the VCU knows whether to end the active regeneration procedure. The method sends the active regeneration state to the VCU in real time, which is beneficial for the VCU to adjust the running mode of the VCU in time according to the active regeneration state.
Optionally, the feedback signal includes an active regeneration interrupt signal for characterizing an interruption of the active regeneration and an active regeneration completion signal for characterizing a completion of the active regeneration.
In the GPF regeneration control method of the embodiment of the present application, the feedback signal includes an active regeneration terminal signal for indicating that the active regeneration process is interrupted, and an active regeneration completion signal for indicating that the active regeneration process is completed.
